Sanoid
These are policy-driven snapshot management and replication tools
...Paired with its sibling syncoid, it also handles local and remote replication of incremental snapshots over SSH, supporting resume tokens, bandwidth shaping, and common accelerators like mbuffer. The design favors safety and observability: dry-run modes, verbose logging, and conservative defaults reduce the risk of accidental data loss. In production, Sanoid turns ZFS’s powerful but low-level primitives into dependable, auditable data protection for everything from home labs to multi-tenant servers.
